Positive Votes Limit

So reading through the forums last night/today, I found out there was a limit on how many times you can press the little +1 button on the bottom of posts. I understand why there's a limit on negs, so some troll doesn't go around negging everyone at random, but why is there a limit on how many times you can +1 posts? Has anyone else ever experienced this?

Yeah, I've pointed this out before too. I assume it has to do with the way the forum is set up. Like if you set a limit of 3 votes, it is the same for both negative and positive. So if you upped it to 7 or something, then you'd be letting people post 7 negs a day as well. I could be totally wrong though...
